Description

Technical Field

[0001] This utility model relates to the technical field of soil analysis devices, and in particular to a soil analysis device for environmental protection testing. Background Technology

[0002] In the field of environmental monitoring, rapid on-site screening of soil pollution is a key link in pollution control and risk assessment. With the acceleration of industrialization and urbanization, the types and contents of pollutants such as heavy metals and organic matter in soil are becoming increasingly complex. Although traditional laboratory testing can provide accurate data, it requires multiple steps such as sample collection, transportation, pretreatment, and instrument analysis, which not only takes several days or even weeks, but also requires professional personnel to operate. It is difficult to meet the needs of on-site real-time testing such as emergency detection of sudden pollution events and rapid survey of large-scale farmland soil.

[0003] Existing soil field testing equipment often has two limitations. First, it can only test a single sample at a time. When multiple comparative analyses are needed on soil samples from different locations in the same area or at different depths of the same location, repeated loading and unloading of samples is required, which is cumbersome and time-consuming, severely impacting testing efficiency. Second, the equipment is bulky and heavy, making it inconvenient to carry and transport, hindering rapid on-site testing, and the testing cycle is long, failing to meet the need for rapid on-site information acquisition. Therefore, to address the shortcomings of existing soil field testing devices in practical use, an environmentally friendly soil analysis device can be designed. By optimizing and combining components such as the analysis box, sample strip, test cover, and control handle, the overall size and weight can be reduced, making it easier to carry. The sample strip has multiple sample holding slots arranged linearly, allowing multiple soil samples to be loaded simultaneously. With the test cover, the testing unit can be installed, enabling multiple samples to be tested in a single operation, thus improving testing efficiency and facilitating the solution of the aforementioned problems. Utility Model Content

[0004] To overcome the shortcomings of existing soil testing devices, which can only test a single sample at a time, severely impacting testing efficiency when multiple soil samples need to be compared and analyzed, and are also bulky and heavy, making them inconvenient to carry and transport, and have long testing cycles, thus failing to meet the need for rapid on-site information acquisition, this utility model provides an environmentally friendly soil analysis device.

[0005] The technical solution is as follows: A soil analysis device for environmental protection testing includes an analysis box, a sample strip, a detection cover, and a control handle; the analysis box has an analysis chamber for analyzing soil samples inside, the analysis chamber has a sample strip for loading multiple sets of soil samples inside, the surface of the sample strip has multiple sample holding slots for mixing acid solution and soil samples linearly, the top of the analysis chamber has multiple detection ports corresponding to the sample holding slots linearly, the detection ports have a detection cover for detecting and analyzing soil samples inside, and one end of the sample strip has a control handle.

[0006] Furthermore, the surface of the detection cover is linearly equipped with multiple indicator light strips, and the bottom center of the detection cover is equipped with interdigitated electrodes that extend to the sample holding slot. Temperature and humidity sensors and spectral sensors are respectively located on both sides of the interdigitated electrodes.

[0007] Furthermore, one end of the detection cover is provided with a movable shaft, and the rear edge of both sides of the detection port is provided with a corresponding movable hole for the movable shaft, with both ends of the movable shaft extending into the interior of the movable hole.

[0008] Furthermore, two sets of sliding grooves are symmetrically provided on both sides of the analysis chamber, and two sets of corresponding sliding strips are symmetrically provided on both sides of the sample strip. An insertion port for the corresponding sample strip is provided at one end of the analysis box, and a data transmission port is provided at the top edge of the end of the analysis box near the insertion port.

[0009] Furthermore, one end of the sample strip is connected to the control handle, and the other end of the sample strip extends through the insertion port into the interior of the analysis chamber. A data transmission head with a corresponding data transmission port is provided at the top edge of the control handle near the sample strip end.

[0010] Furthermore, a display slot is provided on the surface of the control handle, and a digital display screen is embedded inside the display slot. A control compartment is provided at the bottom of the display slot, and a circuit board is provided inside the control compartment. The circuit board, interdigitated electrodes, temperature and humidity sensors and spectral sensors are electrically connected.

[0011] Furthermore, a battery compartment is provided at the lower end of the control handle, and a battery pack is located inside the battery compartment. A battery cover is provided below the battery compartment to close the battery compartment.

[0012] The beneficial effects are as follows: Compared with the shortcomings of existing devices, this application uses a linear array of sample slots on the sample strip to simultaneously load multiple soil samples. Unlike existing soil testing devices that can only test a single sample at a time, this application allows for the testing of multiple samples in a single operation, significantly reducing the time and steps required for repeated sample loading and unloading, and greatly improving testing efficiency. For example, in rapid surveys of large areas of farmland soil, it can quickly obtain testing data from multiple samples, providing timely information on soil pollution. The bottom of the testing cover is equipped with interdigital electrodes, a temperature and humidity sensor, and a spectral sensor. The interdigital electrodes directly contact the sample for electrochemical detection, the temperature and humidity sensor acquires the sample's temperature and humidity information, and the spectral sensor acquires the sample's spectral data. By simultaneously acquiring multi-dimensional data, a more comprehensive analysis of soil pollution can be conducted, reducing the errors that may exist with single detection methods and improving the accuracy and reliability of the test. The optimized combination of components such as the analysis box, sample strip, testing cover, and control handle reduces the overall size and weight. Compared with existing equipment that is large and heavy, making it inconvenient to carry and transport, this application is more convenient for operators to carry to the site for testing. Whether it's emergency testing for sudden pollution incidents or soil testing in remote areas, it can quickly reach the site and carry out testing work, meeting the need for rapid on-site information acquisition.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Example like Figures 1-5 As shown, an environmental protection testing soil analysis device includes an analysis box 1, a sample strip 3, a detection cover 4, and a control handle 5. The analysis box 1 has an analysis chamber 2 for analyzing soil samples inside, and the analysis chamber 2 has a sample strip 3 for loading multiple sets of soil samples inside. The surface of the sample strip 3 has multiple sample holding slots 15 for mixing acid solution and soil samples linearly. The top of the analysis chamber 2 has multiple detection ports 10 corresponding to the sample holding slots 15 linearly. The detection port 10 has a detection cover 4 for detecting and analyzing soil samples inside, and a control handle 5 is provided at one end of the sample strip 3.

[0017] The surface of the detection cover 4 is linearly equipped with multiple sets of indicator light bars 9. The bottom center of the detection cover 4 is provided with an interdigital electrode 12 extending to the sample holding slot 15. On both sides of the interdigital electrode 12 are respectively provided a temperature and humidity sensor 13 (model SHT15) and a spectral sensor 14 (model PL2040 UV-VIS). The multiple sets of indicator light bars 9 can intuitively display the detection status or results of different samples, making it convenient for operators to quickly obtain information. The interdigital electrode 12 can directly contact the sample for detection and analysis. The temperature and humidity sensor 13 and the spectral sensor 14 can simultaneously acquire more data such as the temperature, humidity and spectrum of the sample, improving the comprehensiveness and accuracy of the detection.

[0018] The detection cover 4 is provided with a movable shaft 11 at one end. The rear edge of both sides of the detection port 10 is provided with movable holes corresponding to the movable shaft 11. Both ends of the movable shaft 11 extend into the interior of the movable hole. The detection cover 4 can be opened and closed flexibly through the cooperation of the movable shaft 11 and the movable hole, which facilitates the placement and removal of the sample.

[0019] The analysis chamber 2 has two sets of sliding grooves 7 symmetrically opened on both sides of the side wall. The sample strip 3 has two sets of sliding bars 16 symmetrically opened on both sides of the sliding grooves 7. The analysis box 1 has an insertion port 6 corresponding to the sample strip 3 at one end. The analysis box 1 has a data transmission port 8 at the top edge of the end near the insertion port 6. The design of the sliding grooves 7 and sliding bars 16 enables the sample strip 3 to be inserted into the analysis chamber 2 smoothly and accurately, ensuring the precise docking of the sample and the detection unit. The insertion port 6 facilitates the loading of the sample strip 3.

[0020] One end of the sample strip 3 is connected to the control handle 5, and the other end of the sample strip 3 extends through the insertion port 6 into the interior of the analysis chamber 2. The control handle 5 is provided with a data transmission head 19 corresponding to the data transmission port 8 at the top edge of the end near the sample strip 3. The control handle 5 is connected to the sample strip 3, which makes it convenient for the operator to insert and remove the sample strip 3 through the control handle 5. The data transmission head 19 corresponds to the data transmission port 8 to ensure that the data can be transmitted stably and accurately.

[0021] The surface of the control handle 5 is provided with a display slot 20, and a digital display screen 21 is embedded inside the display slot 20. A control compartment 17 is provided at the bottom of the display slot 20. A circuit board 18 is provided inside the control compartment 17. The circuit board 18, the interdigital electrode 12, the temperature and humidity sensor 13 and the spectrum sensor 14 are electrically connected. The detection data and related information can be displayed in real time through the digital display screen 21, which is convenient for operators to view. The circuit board 18 serves as the control core, coordinating the work of components such as the interdigital electrode 12, the temperature and humidity sensor 13 and the spectrum sensor 14 to realize data acquisition, processing and transmission.

[0022] A battery compartment 22 is provided at the lower end of the control handle 5. A battery pack 23 is installed inside the battery compartment 22. A battery cover 24 is provided below the battery compartment 22 to close the battery compartment 22. The battery compartment 22 and the battery pack 23 provide an independent power supply for the device, so that the device can work without an external power supply, which enhances the portability and applicability of the device. The battery cover 24 can protect the battery pack 23 and prevent the battery pack 23 from falling off or being damaged.

[0023] During operation, first install the fully charged battery pack 23 into the battery compartment 22, ensuring the battery is securely installed. Then, close the battery cover 24. Next, slowly insert the sample strip 3 into the analysis compartment 2 through the insertion port 6. The sliders 16 on both sides of the sample strip 3 slide smoothly along the sliding grooves 7 on both sides of the analysis compartment 2 to ensure that the sample strip 3 is accurately inserted until one end of the sample strip 3 is tightly connected to the control handle 5. At this time, the sample holding slot 15 corresponds accurately to the detection port 10, and the data transmission head 19 is accurately connected to the data transmission port 8.

[0024] During testing, multiple sets of soil samples are collected from different locations or at different depths at the same location according to the testing requirements. Then, the testing cover 4 is opened, and the movable shaft 11 rotates in the movable hole to make the testing cover 4 open flexibly. The collected soil samples are placed into multiple sets of sample holding slots 15 linearly opened on the surface of the sample strip 3. Each sample holding slot 15 holds one set of samples. Then, an appropriate amount of mixed acid dissolving solution is added to each sample holding slot 15 to dissolve the soil samples for subsequent testing and analysis.

[0025] Then close the detection cover 4 to ensure that the detection cover 4 fits tightly with the detection port 10. At this time, the interdigitated electrode 12 at the bottom of the detection cover 4 extends into the sample holding slot 15 and comes into direct contact with the soil sample. The temperature and humidity sensor 13 and the spectral sensor 14 can simultaneously acquire multi-dimensional data of the sample's temperature, humidity and spectrum.

[0026] The collected data is transmitted to the circuit board 18 via the data transmission head 19 and the data transmission port 8. The circuit board 18 processes the data and then transmits it to the digital display screen 21 for real-time display. At the same time, multiple indicator lights 9 display corresponding information based on the detection status or result of different samples. For example, a green indicator light indicates normal detection, while a red indicator light indicates potential contamination or other problems, allowing operators to quickly obtain information.

[0027] Its working principle is that the interdigitated electrode 12 is in direct contact with the soil sample. By measuring the electrochemical characteristics of the sample, the content and type of pollutants such as heavy metals that may exist in the sample can be analyzed. Different pollutants will have different electrochemical characteristics. The interdigitated electrode 12 can capture these subtle changes and convert them into electrical signals to be transmitted to the circuit board 18.

[0028] Temperature and humidity sensor 13 monitors the temperature and humidity environment of the sample in real time. The temperature and humidity of the soil can affect the activity, solubility and chemical reaction rate of pollutants. Obtaining temperature and humidity data can help to analyze the soil pollution status more accurately. Under high temperature and high humidity conditions, the volatility of some organic pollutants may be enhanced. The data obtained by temperature and humidity sensor 13 can provide important reference for subsequent analysis.

[0029] The spectral sensor 14 utilizes the principle that different substances have different absorption, reflection and scattering characteristics of light to perform spectral analysis on soil samples. Different pollutants have unique spectral characteristics, and the spectral sensor 14 can capture these characteristic spectra to identify pollutants such as organic matter in the sample and make a preliminary judgment on their content.

[0030] Its beneficial effects are significant. This application uses sample strip 3 to linearly open multiple sample holding slots 15, which can simultaneously load multiple soil samples. Compared with existing soil on-site testing devices that can only test a single sample at a time, this application enables the testing of multiple samples in one operation, greatly reducing the time and operation steps of repeatedly loading and unloading samples, and significantly improving the testing efficiency. For example, when conducting rapid surveys of large-area farmland soil, it can quickly obtain the testing data of multiple samples and promptly understand the soil pollution status. The bottom of the testing cover 4 is equipped with interdigitated electrodes 12, temperature and humidity sensors 13, and spectral sensors 14. The interdigitated electrode 12 directly contacts the sample for electrochemical detection, the temperature and humidity sensor 13 acquires the sample's temperature and humidity information, and the spectral sensor 14 acquires the sample's spectral data. By simultaneously acquiring multi-dimensional data, a more comprehensive analysis of soil pollution can be achieved, reducing the errors that may exist with single detection methods and improving the accuracy and reliability of the detection. The analysis box 1, sample strip 3, detection cover 4, and control handle 5 are optimized and combined to reduce the overall size and weight. Compared with existing equipment that is large and heavy and inconvenient to carry and transport, this application is more convenient for operators to carry to the site for testing. Whether it is emergency detection of sudden pollution events or soil testing in remote areas, it can quickly reach the site and carry out testing work, meeting the need for rapid on-site information acquisition.
